I've previously worked at a company using an "open source" license (Elastic, with the ELv2) and have enjoyed having to explain the difference to folks between what it meant to be "open source" vs "Open Source", and the fact that a lot of folks generally don't understand the difference and some of the nuance. Mentioning the BuSL was because it's something a lot more folks may be aware of, i.e. given Hashicorp's recent relicense (as with other companies in recent years)
Sustainability is hard, and having different ways to describe this is good! But it's a lot harder when people don't understand why something calling itself "open source" when it's "but you can't run it if you're a company" is bad
